CHUTE DISCHARGE UNIT Filed Nov. 22. 1930 Wfisses: bave/75W d', jyGa/)z-eawez/g Patented Nov. 17, 1931 PATENT OFFICE GAIL D. BEAVER, OFNORRISTOWN, PENNSYLVANIA I 'i CHUTE DISCHARGE UNIT Application filedNovember 22, 1930. Serial No. 497,387.

My invention relates to the boot and boot casing of a chute for linen orthe like, with particular reference to the support of the casing.

A purpose of my invention is to provide the upper section of a'bootcasing of the character indicated with a support from above asdistinguished from a support from below.

A further purpose is to provide a boot casing ofthe character indicatedwith a three-point support; one at each side from above near its upperend, and one at the middle from below on the lower and more forwardsection of the boot Casing. Y

Furtherpurposes will appear in the speciiication and in the claims.

I have elected to show one only ofthe many different forms' of myinvention, selecting a form that is practical and efcient in operationand which well illustrates the principles involved.

Figure 1 is a fragmentary side elevation illustrating structureembodying one form of my invention. i

Figure 2 is a left side elevation of structure shown in Figure 1.

Like numerals refer to like parts in both figures.

Describing in illustration and not in limitation and referring to thedrawings My invention is believed to find its best application withlinen chutes, such as are used in multistory buildings, the chute oftenrunning from the top floor to the basement with inlets at the individualfloors and an elbow outlet, technically known as a boot, in the basementsupported within and by a boot casing that is to be desirably supportedby mechanism lembodying my invention.

The chute proper 6 is made of thin sheet material, preferably aluminumor other metal unable to stain linen passing down the chute, the lowerend of the vertical body (i fitting inside the upper and verticalinletsection 7 of the three-section boot 8 which has a lateral outlet at9 normally closed by a suitable door 10.

The boot comprises a three-section elbow with the upper and lowersections 7 and 11 respectively vertical and horizontal and theintermediate section 12 having a forty-five degree slope.

The bootwill normally be of the same ma- Y terial as the chute body,usually aluminum or an aluminum alloy, and of gauge too light topermanently withstand the often repeated sudden shock stresses incidentto dropping linen or the like down the chute and having it strike theupwardly directed inclined inner surface of the boot section 12.

The boot is protected and supported by a casing 13 that includes thenon-vertical sections 11 and 12 of the boot and is divided at 14 alonghorizontally opposite sides, the upper and lower divisions of the bootCasing being fastened together after installation along mating flangesat 14, as by riveting, bolting or welding.

l show a drain pipe iiange 15 on the bottom of the casing, a littlerearward of the door, the boot being provided with a corresponding drainconnection into a drain pipe carried by the flange 15.` i

The upper end of the upper boot section 7 receives the downwardlydirected end of the body 6. Relatively heavy brackets 16, desirablysteel and riveted to the chute section at circumferential intervals,each present a top horizontal face to a mating bottom face of acorresponding bracket 17 of the main chute 6.

The horizontal top faces of the heavy brackets 16 are preferably evenwith the top edge of the boot section, the inner ends of the rivets 18thathold the brackets to the boot section7 being covered when in placeby the downward overlap of the chute section 6. i

The brackets 17 of the upper section are preferably of the same materialas the body ofthe chute, as light sheet aluminum, with their upwardlyextending vertical portions desirably welded to the body of the chute.

The outwardly extending portions of the light brackets 17 rest on thehorizontal faces ofthe heavy brackets 16 being clamped between the upperfaces of the heavy brackets 16 and relatively heavy plates19 by suitablebolts 20.

The bottoms of the light brackets form stops that limit and register theoverlap between the chute body and the boot section 7.

I provide the boot casing with a three-point support, from above atpoints on substantially opposite sides of the vertical center line ofthe chute at 2l and 22 and from below at 23 directly under the middle ofthe boot casing toward the rearward end of the horizontal section of thecasing, thaiJ is near the lower end of the intermediate sloping section7and preferably vertically below the main chute 6 near the forward sidethereof.

I find that this type of support is particularly effective in preventingstrains incident to use.

The lateral hanger rods 2l and 25 make adjustable connection at thebottom with lateral ears from the boot casing at the points 21 and 22,these ears being` integral with or rigidly connected to the lowerdivision of the casing.

The hangers 2a and 25 are supported at their upper ends upon suitable.supporting structure 26 that may form part of or be carried by thesuperstructure of the building.

The divided casing may be made of sheet steel, the ear brackets at 2land 22 being welded or otherwise fastened to the upper end of the lowerhalf of the casing on opposite sides of the center line of the. body ofthe chute.

rIhe support 27 from below is desirably a structural member such as achannel, bolted at the top to a suitable downwardly extending bracket 28welded or otherwise connected to the casing and fastened at the bottomas at 29 to a suitable concrete foundation.

In view of my invention and disclosure variations and modifications tomeet individual whim or particular need will doubtless become evident toothers skilled in the art, to obtain all or part` of the benefits of myinvention without copying the structure shown7 and I, therefore. claimall such in so far as they fall within the reasonable spirit and scopeof my invention.

Having thus described my invention. what I claim as new and desire tosecure b v Letters Patent is 1. In chute mechanism of the characterindicated, a boot, a casing about a lowerand forward portion thereof anda three-point support for the casing including a support from above oneach side of the casing and a support from below, said points beinglocated so that the median point of a triangle having said points asapices will be on a vertical line well within the contour of the mainvertical chute.

2. In chute mechanism of the character indicated, a boot, a casing abouta lower and forward portion thereof and a three-point support for thecasing including a support from above on each side of the casing and asupport from below, said support from be low being on a vertical linewithin the horizontal section of the main vertical chute and thesupports from above being at opposite ends of a line within a verticalplane cutting` the main chute longitudinally and spaced horizontallyfrom the point of support from below.

3. In chute mechanism of the character indicated, a boot, a boot casingabout a lower portion thereof and a three-point support for the casingincluding a support from above on each side of the casing and a supportfrom below, said support from above being from points on substantiallyopposite sides of the center line of the chute and the support frombelow from a point below the main chute section near the forward sidethereof.

a. In chute mechanism of the character indicated, a boot including avertical inlet section, an intermediate sloping section and a horizontaloutlet section, a boot casing about the intermediate and outletsect-ions and a. three-point support for the casing ineluding a supportfrom above on each side of the casing on substantially opposite .sidesof the vertical center line of the chute and a support from below underthe outlet section of the chute.

5. In chute mechanism of the character indicated, a boot, a divided bootcasing having a lower division separated from an upper division alonglines at substantially horizontally opposite sides of the casing and athreepoint support for the said lower division including a support fromabove on each side of the casing and a support from below, said supportsfrom above being from points on substantially opposite sides of thevertical.

center line of the chute and the support from below from a. point belowthe main chute scction near the forward side thereof.

G. In chute mechanism of the character indicated, a vertical chute bodyof light sheet aluminum having a downwardly directed end, outwardlyextending light sheet ears welded thereto at intervals around thecircumference near and spaced from the bottom edge thereof, an aluminumboot having a vertical end fitting around the lower end of the body,heavy brackets on the inlet end of the boot under the ears, meansclamping the ears to the brackets, a boot casing about the lower andforward portion of the boot and a three-point support thereof includinga support from above on horizontally opposite sides of the casing and asupport from below spaced forwardly from the supports from above.
